Hello Mt.Fuji members,
We found one inconsistency in the description of the Address Mode
Reservation within Mt.Fuji6 Rev1.00.
In section 4.18, followings are described;
  In the case of DVD-R Incremental Recording mode, when NWA of the
  Incomplete Track/RZone is specified as reservation address, the
  recorded part of the Incomplete Track/RZone changes to Complete
  Track/RZone as shown in Figure 99. Unrecorded part changes to
  Invisible Track/RZone. When higher address than the NWA is specified
  for reservation address, a Reserved Track/RZone and new Invisible
  Track/RZone are made.
By this description, the Address Mode Reservation is allowed to be
applied to the Incomplete RZone on DVD-R disc when the disc is in
Incremental Recording mode.
But on the other hand, the reservation is allowed only from the first
sector of the invisible RZone as described in section 4.16.7.4 RZone
reservation scheme as follows;
  RZone shall only be reserved from the NWA of the invisible RZone. If
  an incomplete RZone exists, the incomplete RZone shall be closed prior
  to reserving a new RZone. The start address of the new Invisible RZone
  is the NWA of the previous incomplete RZone.
The latter description is very old and it was left behined the revision
when the Address Mode Reservation was introduced. The above limitation
is only for the Size Mode Reservation. So, it must be revised like as
follows;
  In case of Size Mode Reservation, RZone shall only be reserved from
  the NWA of the invisible RZone. If the RZone is the incomplete RZone ,
  the RZone shall be closed prior to making the reservation. The start
  address of the new Invisible RZone is the NWA of the previous
  incomplete RZone.
